Eviscerate and heat stack

Just starting off the bat with this I'm working with Shelby Starnes so my diet is fine.

I am using eviscerate 2 squirts 2x daily 8 hours apart on the abs. I want to add in the heat stack. What would be a safe dose to add in the heat stack. I am using hte original eviscerate. I would even be fine uping the dose of the eviscerate even though it does hurt as it works so well. I have only a few more weeks to hit the goal
